How to get what I need to continue being a loyal Vodacom customer

I have 4 Vodacom contracts and in general I have been pretty happy with them. I now live in an area where reception is pretty bad. So now I want to get a reception boosting device installed, but everyone I contact refers me to someone else. I've traveled 100km to find someone to give me a booster and no one can help. I have cancelled one of my contacts with Vodacom already and I'm a matter of hours away before I sign up for a contract with another service provider This is my last cry for "HELP!" before I say cheers to Vodacom.
